Application filed June 6,1905. seiiairazcaeis.

To all whom/ it puny concern.-

Be it known that I, JOHN THOMAS, a subject of the King of Great Britainand Ireland, and a resident of Oaludon House, near Coventry,lVarwickshire, Englanchhave invented certain new and useful ImprovedMeans for Imparting Motion or Power, (for which I have filed anapplication for British patent, No. 16,651, dated July 2-8, 1904;) and Ido hereby declare the following to be a full, clear, and exactdescription of the same.

This invention relates to means for imp arting motion or power from onepart, hereinafter, by way of example, referred to as a lever, to anotherpart, hereinafter, by way of example, referred to as a brake-shoe, at adistance, whether or no the connecting means, hereinafter referred to asthe operating wire, be taut or loose between such parts, and has for itsobject to sheath the operating Wire by metallic means which, while beingcompressible and extensible endwise and flexible all ways, will act as acover to the wire and also as a guide thereto if not otherwise guidedwhich will protect it from the access of wet dust and other influencesliable to interfere with its working and from abrading adjacent parts inits working and will not be subject to the liability of getting crushedor catching fire and other disadvantages incidental to inextensible andin compressible sheathing means composed of gutta-percha or celluloid.

' To this end, the invention consists in the combination with such meansand parts for imparting motion and power, and so as to inclose saidwire, of a flexible compressible and extensible coiled metallic tubehaving a metallic interior and exterior and being impervious to Wet anddust at its convolutions, and hereinafter further referred to as the me'tallic tube.

On the accompanying drawings. Figure, 1, represents part of a cycleframe, shown, by way of example, as means for locating the prime moverand the part to be operated, and showing an arrangement in which theoperating wire is stretched taut between a brake lever and a brake shoeand is supported at the bends it has to negotiate by clips or the like.Fig, 2, is a detail view of such arrangement, showing the operating wireinclosed by the metallic tube. I

(i, represents the brake lever, b, the brake What I claim as myinvention and desire to secure by Letters Patent is 1. In means fortransmitting motion, in combination, a taut operating wire and anaxially compressible metallic tube formed of a strip having a doublealternate channel for mation and helically coiled so that the outerparts of adjacent convolutions overlap and underlap one anotherrespectively, the wire being movable axially within said tube.

2. In means for transmitting motion, in combination, a taut operatingwire, an axially compressible metallic tube formed of a strip having adouble alternate channel formation and helically coiled so that theouter parts of adjacent convolutions overlap and underlap one anotherrespectively, and a yielding packing located between abutting points ofthe convolutions of the strip, the Wire being movable axially withinsaid tube.

3. In means for transmitting motion, in combination, a taut operatingcable and a flexible and axially compressible and extensible metallictube made of a strip having a double alternate channel formation andhelicially coiled so that the outer parts of adjacent convolutionsoverlap and underlap one another respectively, said cable being movableaxially within the tube.

4. In means for transmitting motion, in combination, a taut operatingcable, a flexible and axially compressible and expansible.

metallic tube made of a strip having a double alternate channelformation and helically coiled so that the outer parts of adjacentconvolutions overlap and underlap one an other respectively, and. ayielding packing located between the abutting points of the strip, saidcable being movable axially within said tube.

5. In means for transmitting motion, in

shoe, 0, the operating wire, and (Z, a cyclecombination, a prime movingpart, a part to IIO be operated, a taut operating cable having its endsrespectively connected to said parts and a flexible and. axiallycompressible and extensible metallic tube made of a strip having adouble alternate channel formation and helically coiled so that theouter parts of adjacent convolutions overlap and underlap one anotherrespectively, said cable being movable axially within said tube.

6. In means for transmitting motion, in combination, a prime movingpart, a part to be operated, a taut operating cable having its endsrespectively connected to said parts, a flexible and axiallycompressible and extensible metallic tube made of a strip having a I 5double alternate channel formation and helically coiled so that theouter parts of adjacent convolutions overlap and underlap one anotherrespectively, and a yielding packing located between said outer parts,said cable being movable axially within said tube.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

JOHN THOMAS.
